No title head?! Anyway, this post is regarding Video Streaming Diagnostic Tests which I conducted last week and some modifications done on SLi .

The table below will show factors such as resolution, compressor type, quality and FPS (Frames Per Second) during video playback and the all important data rate (which shows the amount of bandwidth the video uses). The data rate however has no limit so bandwidth usage can get atrociously high. I'll conduct a future test with date rate limiting taken into account.

Resolution Compressor Quality FPS Data Rate [Min/Max]
160 X 120 MPEG-4 Medium 25 [68kbits/s][435kbits/s]
=> Very Poor
160 X 120 MPEG-4 High 25 [430kbits/s][943kbits/s]
=> Poor
160 X 120 MPEG-4 Best 25 [953kbits/s][1880kbits/s]
=> Average
320 X 240 MPEG-4 Medium 25 [92kbits/s][420kbits/s]
=> Rather poor
320 X 240 MPEG-4 High 25 [880kbits/s][2185kbits/s]
=> Average
320 X 240 MPEG-4 Best 25 [3366kbits/s][4941kbits/s]
=> Good
640 X 480 MPEG-4 Medium 25 [410kbits/s][2950kbits/s]
=> Very Good
640 X 480 MPEG-4 High 0.3 [-][-]
=> Not able to broadcast

Based on the data I collected, it seems the test that yielded very good image quality as compared to the others would be the best settings. However, the macintosh computer isn't able to broadcast videos with a resolution higher than 640 X 480.

On to SLi, I've done some extensive landscaping on the island; mostly consisting of natural features such as cliffs, edge ripples and rivers. Images will be coming soon together with the additional tests.
